Answer:

216 x 16

Explanation:

Given

  • 6³ x 4²

Simplify into prime factors.

  • (2 x 3)³ x (2²)²
  • 2³ x 3³ x 2⁴
  • 2⁷ x 3³
  • 128 x 27
  • 3456

Now, for it to be equivalent, on dividing 3456 by the product of the expression, the quotient should be 1.

Evaluating the options

18 x 8

  • 3456 ÷ (18 x 8)
  • 3456 ÷ 144
  • 24
  • Incorrect

216 x 16

  • 3456 ÷ (216 x 16)
  • 3456 ÷ 3456
  • 1
  • Correct

24⁶

  • 3456 ÷ 24⁶
  • 3456 ÷ 191102976
  • Answer will be less than 1, so this isn't it
  • Incorrect

(6 x 4)⁵

  • 3456 ÷ (6 x 4)⁵
  • 3456 ÷ (24)⁵
  • 3456 ÷ 7962624
  • Here also the quotient will be less than 1
  • Incorrect

216 x 16 is the correct answer
